`Lette/rs Patent No. 92,048, dated Jsme 29, 1869.

IMPROVEMENT IN BREECH-LOADING- FIRE-ARMS.

The Schedizle referred to in these Letters Patent` and making part of the same.

To whom it may concern Be it known that I, MATHIAs J. HINDEN, of Detroit, in the county ot' Wayne, and State of Michigan,

have invented a new and useful Improvement in NeedleGun`s; and I do declare that the following is atrue and accurate description thereof, reference being had to the accompanying drawings, and to the lettcrsof reference marked thereon, and being a part of this specilication.

Figure l is a perspective view of my improvement.

Figure 2 is a longitudinal sectional view of the same. Figure 3 is a plan view of the steel tube.

Figure 4 is a plan of cylinder.

Figure is a plan of lever and sleeve.

Figure 6 is a plan of needle-stock and needle.

Figure 7 is a section of the same, on the line x of tig. 6.

Figure 9 is a plan view of' safety-guard.

Figure l() is a side view ofthe same.

Like letters indicate like parts in each ligure.

The object of this invention is so to construct a gun, as that it may be rapidly loaded at the breech, and discharged bymeans ofa needle, perforating the fulininator ot' a proper cartridge, that will be so simple in its construction, that there is very little liability of its getting out of order, and so that it can be made safe from premature discharge, by a proper safetyguard.

In the construction of this gun, I use a new combination of parts which are old, or of doubtful novelty, except the saiety-guard, which I beiieve to be my own invention.

In order to accomplish this end, I construct a stock, A, to which I attach a barrel, B, by any proper means, `the rear end of the same being conical in shape, as at W, in tig. 2. v

'Ihe bore of this barrel is enlarged, as at X, in the same iigure, the more readily to receive the necessary cartridge.

In a suitable groove, Y, in the stock, I fasten a steel or metal tube, C, provided with angular slot K, by means of which the cylinder. D is controlled in its movements.

'Ihe needle-stock G has loosely sleeved upon 'rt the lever E, by means of which the cylinder is moved forward or backward, as may be desired, the two ends of the cylinder, 5 and 6, forming collars to hold thc same in place, and being screwed together, asat 7, in tig. 2.

Itis also provided with a rigid guide or stop, L, which, engaging with the angles of the slot Ii, prevent the cylinder from dropping out of the tube C.

Within this cylinder, works the needle-stock G,

Figure 8 is a section of cylinder', on the line -y y of l carrying the n eedle` H, which is attached tosaidstock, which is provided with a collar, Z, and stop N, and is surrounded by spiral spring M.

The cylinder is also provided with slot Q, within which the stop N works.

, Attached to the rear end of the cylinder D, is the lsatety-gnard I, provided with slide plate It, which,

being raised, engages with the dat planes S upon either side of the needle-stock G, and prevents a premature discharge of the gun.

The slot K, in the tube O, should be enlarged, as at 3, in tig. 3, to allow room for the insertion of' the cartridge into the rear end of the barrel, and one fractional end of the slot J, should be ari inclined plane, to allow the lever E to lock against the incline ot' the plane, and hold the conical end U, of the cylinder D, against the conical end of the barrel.

The cylinder l) is provided with a recoil-chamber, V, the mouth of which is chamfered to fit, over the Yconical end of thebarrel, before described.

y O is an extension of the trigger I?, which projects upwards through the tube G, and acts as a stop against the stop N, and prevents the recoil of the spring M which forces the 'needle H forward through the end of the cartridge. By pulling the trigger P, the extension O, of the same, is withdrawn, when the recoil ofthe spring M forces the needle forward int the cartridge, and into contact with the fulminator.

Tis a? trigger-guard of the ordinary construction, and for the listini purpose.

'Io operate this gun, requires a peculiar cartridge, upon the construction of which I am about to apply for Let-ters Patent. r

We will suppose the gun and cartridge 'to both be ready for work, and the gun to have just been discharged.

Nith the right hand I disengage the lever from the inclined plane of the slot, by turning it to the left until it is tlush with the stop L; then drawit backward, and by its means the cylinder, wit-hin which is the needle-guard und needle, until the stop L reaches and is stopped bythe angle 4, ofthe slot,'when a sul'icient space will be opened in the enlargement 3, of the slot,

Ito insert the cartridge into the rear endet' the barrel B.

After the cartridge is thus inserted, push the lever forward again until it reaches the enlargement of the slot 3, and turn it to the right until it engages with the inclined plane heretofore mentioned. By this operation the chamfered and conical end of the cylinder shuts over and against the conical end of the barrel, thereby making a very close joint and abutment to withstand the explosion ot' the cartridge, and consequent recoil. In moving the lever torward, as described, it carries with it the cylinder' I) and needlestock G, until the stop N is engaged with the extension 0, of the trigger, which prevents the needle-stock from going any further.

lhe continued forward motion ofthe lever and cylinder, until the end thereof engages with the barrel as before described, compresses the spiral spring M,

which compression is only relieved by the removal oi" the extension O, ofthe trigger, which is done by pulling said trigger, when the recoil of the Aspring forces the needle-stock and needle forward until the latter has punctured the fulminator of` the cartridge, when the gun is discharged.

when arranged and' operating for thepurpose aforesaid. Y
